Set the desired data logger recording rate (see the "Adjusting Data Logger Recording Rate" section).
To toggle data logging On/Off, press and hold the SET button for 6 seconds (each time this is performed, it will toggle
from on/off and from off/on):
OFf rEc indicates that the data logging function is off.
ON rEc indicates that the data logging function is on.
While data logging is occurring, the clock section will alternate between displaying the time and rEc.
If the meter is turned off, the data logging will also be turned off. When the meter is turned on, data logging
must be turned back on by using the above procedure.
If the SD card is removed while data logging is turned on, Err and Sd will alternate on the display in place of the clock to
indicate that the meter is no longer recording data. Insert the SD card to return to data logging.
The following will cause data logging to stop/turn off:
• Turning the meter off
• Low battery power (), when using batteries only
• Power failure, when using the AC power supply only
• Removing the SD memory card
• Changing the time-of-day/date
• Changing the data logger recording rate
• Changing the High/Low alarm settings
• Changing display from °F/°C, °C/°F
• Pressing the RESET button
Once data logging has been stopped, it must be turned back on.
DATA LOGGING FILE FORMAT/STRUCTURE
With data logging turned on (see the "Turning On/Off Data Logging" section), the meter will write a file to the SD
memory card. The file created is a standard text (.TXT) file.
Once data logging has started, the filename created is based on the start date (month and day number) and time.
